GLOBE-FASTENER.

Specification of Letters Patent.

Patented Sept. 10, 1907.

Application filed July 8,1905. Serial No. 268,892.

To all whom it may concern:

Be it known that I, LENNA G. Dunn, a citizen of the United States, residing at Colorado Springs, in the county of El Paso and State of Colorado, have invented a new and useful Globe-Fastener, of which the following is a specification.

My invention relates to certain new and useful improvements in globe fasteners, and especially those adapted to be applied to electric sockets and has for its object to provide a fastener that can be attached to any socket.

Another object of the invention is to provide a globe fastener with spring actuated jaws, so that the globe can be inserted or removed with the greatest of ease and at the same time will be securely held therein when closed.

A further object of the invention is to provide a globe fastener which is very simple and cheap in construction, and one that can be operated with one hand, so that the globe can be inserted or removed with the other, as may be desired.

With these objects in view, my invention consists of the novel features of construction, and arrangement of parts hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this speciflcation: Figure 1 is a perspective view of the fastener applied to a socket supporting a globe. Fig. 2 is a sectional view of a socket and fastener showing the globe attached. Fig. 3 is a top plan view of the fastener partly in section. Fig. 4 is a perspective view of the fastener, and Figs. 5 and 6 are detail views. Fig. 7 is a detail view of the clamping flange.

Referring to the drawings, A, indicates a circular plate provided with outwardly projecting arms A and a central opening A having an upwardly projecting flange A, split away at A and its end bent outwardly forming perforated cars A, and A, the ear A, being screw-threaded, and is adapted to receive the screw N, which passes through the opening in the ear A and draws the flange tightly around the socket I, and securely lock it thereto.

Secured to one of the arms, A, is a supporting arm B, carrying a pin 13, which. passes through ears 0, and

D, formed on the wings C and D of the plates (1,,

and D, and is surrounded by a coil spring B the ends B and B ofwhich extend outwardly between the wings O and D and hold them apart.

Carried by the plates 0, and D, are the curved jaws E, and F, provided with grooves E and F, formed by the upper square flanges E and F and the lower beveled flanges E and F adapted to receive the flange of the globe H, which is securely clamped therein by the action of the spring between the arms A, which fits under the upper flanges E and F when closed, and the lower flanges E and F.

To limit the outward movement of the jaw, I secure to the wall of the groove E of the jaw E, a curved plate G, by the pin G, which is provided at its other end with a pin G adapted to slide in the slot F, formed in the wall of the groove F of the jaw F.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. A globe fastener comprising a plate, provided with a central opening, having a clamping flange extending up wardly therefrom, of grooved clamping jaws pivotally connected to said plate, and spring means connected to said jaws for closing said jaws, for the purpose described.

2. A globe fastener Comprising a plate, having arms extending therefrom, an opening formed in said plate, provided with an upwardly extending clamping flange, the ends of said flange being connected together by an adjusting screw, of spring actuated jaws carried by said plate and means connected to said jaw for opening said jaws, for the purpose described.

3. A globe fastener comprising a plate provided with clamping members, of clamping jaws carried by an arm secured to said plate, plates secured to said jaws having wings provided with ears, a pin passing through the supporting arm, and said ears, and spring means carried by said pin for closing said jaws, for the purpose described.

4. In a globe fastener, the combination with a plate provided with a central opening having an upwardly extending flange provided with outwardly extending perforated ends, of grooved jaws carried by said plate, one of the jaws being provided with a slot in the wall of the groove, a curved plate carried by the other jaw provided with a pin working in said slot, and means connected to said jaws for operating the same.

5. In a globe fastener, the combination with a plate having outwardly projecting arms, a central opening formed in said plate provided with an upwardly projecting flange, cutaway adjacent to one end, the ends of said flange being turned outwardly forming perforated cars, a screw adapted to work in said ears, of spring actuated grooved jaws carried by an arm connected to said plate, and means connected to said jaws for limiting the outward movement of the same, for the purpose described.

6. In a globe fastener, the combination with a plate provided with outwardly projecting arms, a central opening formed in said plate provided with an upwardly projecting flange having outwardly extending apertured ends, the flange being cut away from the plate adjacent one end, a screw adapted to work in said ends, of an arm secured to one of the arms of the plate provided with a downwardly projecting pin, wings mounted on said pin, a coil spring surrounding said pin, the ends of which engage the wings,

and grooved jaws connected to said wings provided with means for limiting the outward movement of the same, for the purpose described.

7. In a globe fastener, the combination with a plate having outwardly projecting arms, of a central opening formed in said plate provided with an upwardly projecting; flange cut away adjacent one end, grooved jaws pivoted to said plate and spring means for holding said jaws around said plate, for the purpose described 8, In a globe fastener, the combination with a plate having outwardly extending arms and a central opening, of clamping members surrounding said openings, a supporting arm secured to one of the arms of said plate, plates provided with wings pivoted on a pin carried by said sup porting arm, grooved jaws carried by said plates, and a spring surrounding said pin adapted to throw the jaws into engagement with the arms of the plates, for the purpos described LENNA G.
